Cutting-Edge Neuroscience Research at UCLA: A Comprehensive Overview

Introduction

The Neuroscience Home Area at UCLA stands as a beacon of interdisciplinary research, fostering innovation by converging analytical tools from diverse disciplines to unravel the complexities of neural function. With a strong emphasis on collaboration and close student-faculty relationships, UCLA's neuroscience program cultivates a vibrant community where students are viewed as junior colleagues, actively participating in shaping their education. Boasting a distinguished faculty of approximately 100 members, the program spans virtually all areas of neuroscience, making significant contributions to the understanding of the brain and nervous system. Supported by substantial federal grants, UCLA's Brain Research Institute (BRI) holds the #1 position in Neuroscience Research Programs nationwide.

Focused Areas of Neuroscience Research

Several areas within UCLA's Neuroscience program are represented by large, collaborative groups of faculty with shared interests. These "Focused Areas of Research" (FARs) drive innovation and discovery. Some of the key research areas include:

1. Neurodevelopment and Neuropsychiatric Traits

Genetic Basis of Neuropsychiatric Traits: Researchers like Sophie X. Deng, Jie J. Zheng, and Olujimi A. Ajijola delve into the genetic underpinnings of neuropsychiatric conditions, seeking to identify specific genes and pathways that contribute to these disorders.
Regulation of Cell Fate: Steven A. Barnes focuses on understanding how cell fate is specified during normal human cortical development and in the context of glioblastoma. He employs single-cell approaches and cortical organoid models to gain insights into these processes.
Mechanisms of Neocortical Development and Neuropsychiatric Disease: Steven C. Cramer utilizes neural stem cell models and bioinformatic approaches to elucidate the mechanisms underlying human neocortical development and the pathogenesis of neuropsychiatric diseases.
Neurogenetics and Systems Biology of Neurodevelopmental Disorders: Deng's work extends to the neurogenetics and systems biology of neurodevelopmental disorders, aiming to understand how genetic factors interact with environmental influences to shape brain development and function.

2. Neural Control of Autonomic, Breathing, and Cognitive Functions

Neural Control Mechanisms: Jeffrey M. Donlea investigates the neural circuits responsible for controlling autonomic functions, breathing, and cognitive processes. Understanding these mechanisms is crucial for developing treatments for a range of neurological and respiratory disorders.

3. Emotional Memory and Disease States

Cognitive and Neural Mechanisms of Emotional Memory: Researchers explore the cognitive and neural mechanisms underlying emotional memory in both healthy individuals and those with disease states. This research seeks to understand how emotions influence memory formation, storage, and retrieval, and how these processes are disrupted in conditions like post-traumatic stress disorder (PTSD).

4. Sensory Perception and Decision-Making

How People See and Why They See The Way They Do: Researchers investigate the neural processes involved in visual perception and how these processes influence decision-making. This research has implications for understanding visual disorders and developing new technologies for visual perception.

5. Synaptogenesis, Circuit Assembly, and Neural Dynamics

Synaptogenesis and Circuit Formation: Researchers focus on understanding the molecular and cellular mechanisms that govern synaptogenesis, circuit assembly, and the cellular basis of neural dynamics. Understanding these processes is essential for understanding how the brain develops and functions.

6. Internal Sensations

Neural Mechanisms of Internal Sensations: X. Yang investigates the neural mechanisms underlying internal sensations, focusing on how we feel inside our bodies. The research specifically examines the molecular and circuit mechanisms of nausea, with the goal of developing new treatments for this debilitating symptom.

7. Structural Neuroscience

Cryo-Electron Microscopy Studies of Synaptic Receptors: Z. Zhou employs cryo-electron microscopy (cryoEM) to study the structures of synaptic receptors, neuronal infections, and neurodegenerative diseases. This structural information is crucial for understanding how these molecules function and how they are affected by disease.

8. Molecular Mechanisms of Neural Development

Molecular Mechanisms of Neural Development: Larry S. Zipursky investigates the molecular mechanisms that govern neural development, with a focus on understanding how neurons connect and form functional circuits. This research is essential for understanding how the brain develops and how developmental disorders arise.

Interdisciplinary Approach

UCLA's Neuroscience Home Area emphasizes the integration of diverse disciplines to tackle complex questions about neural function. This interdisciplinary approach is reflected in the program's research areas, which often involve collaborations between faculty from different departments and schools. For example, researchers may combine molecular techniques with imaging technology to understand the cellular and behavioral phenomena, or apply novel developments in basic science to elucidate clinical problems.

Impactful Discoveries and Contributions

UCLA researchers have a long history of making groundbreaking discoveries that have had a significant impact on the field of neuroscience and on human health. Some notable achievements include:

Nicotine Patch for Smoking Treatment: UCLA researchers developed the nicotine patch, a revolutionary treatment for smoking cessation.
Secondhand Smoke Effects on Brain Chemistry: Research at UCLA demonstrated that secondhand smoke can affect brain chemistry and function, raising awareness of the dangers of passive smoking.
Cloning Brain Targets for Opiate Drugs: UCLA researchers successfully cloned brain targets for opiate drugs, providing insights into the mechanisms of addiction and pain relief.
First Imaging Studies of Drug Craving: UCLA scientists conducted the first imaging studies of drug craving in humans, shedding light on the neural circuits involved in addiction.
Miniscope Development: UCLA researchers developed the miniscope, a miniature microscope that allows for the imaging of neural activity in freely behaving animals. This technology has led to a better understanding of how the brain links memories across time and how spatial coding breaks down in epilepsy.
Addiction Services Worldwide: UCLA has led efforts to introduce addiction services in many parts of the world, working with organizations like the WHO, the UN, the Department of State, and the State of California.

Opportunities for Students

UCLA's Neuroscience program provides numerous opportunities for students to engage in research and gain valuable experience.

Early Engagement

Office Hours: Students are encouraged to attend office hours from their first year to connect with professors, ask questions, and learn about their research.
Volunteering: While not recommended during the first year due to academic adjustments, volunteering in a laboratory or hospital is encouraged starting the summer after the first year.

Research Opportunities

SRP-99: In their second year, students can identify faculty with Academic Senate titles (Assoc Prof, Asst Prof, and Prof, including "In Res" titles) to begin SRP-99 research. The UCLA Directory helps verify titles.
Major Capstone: Junior and senior years offer the chance to start a major capstone with NEUROSC 199A (or NEUROSC 198A for Departmental Honors students).
Transfer Students: Transfer students can follow similar procedures to begin volunteer work and choose a research sponsor.
Prerequisites: One quarter of SRP-99 or departmental 199 in the lab and NEUROSC M101A are enforced prerequisites for both NEUROSC 198A/199A.
Research Commitment: Students completing research for the neuroscience major must dedicate two quarters of upper-division research in the same lab.
